Question

A bus starts from rest and attains a speed of 54 km per hour in 10 seconds. Calculate acceleration

Answer 1

Initial velocity (u)= 0
Final velocity (v) = 54km/h
= 15m/s
Time (t) = 10s
Acceleration (a) = (v-u)/t
=(15-0)/10
=15/10
=1.5m/s^2

Answer 2

Answer:

initial velocity = 0

final velocity= 54×5/18

= 15m/s

time= 10second

acceleration = v-u/ t

acceleration = 15-0/10

1.5m/s sq
